This shelf is primarily for use as a stepping stone. Its not quite large enough for most cats to lay on, but is the perfect size for hopping to another shelf. The top of each shelf has multiple layers of fabric; our cats climb on them and jump around the wall with ease. Our cats love the rougher feel of the burlap fabric, which they use to scratch their face with. Beware your cats may fly across the room to jump onto these, but the burlaps amazing grip will allow them to pull themselves right up onto the shelves. These shelves come with two brackets attached to them, with one bracket meant to be mounted into a stud and the other to be mounted into drywall with anchors. All of our furniture also comes with screws and drywall anchors. When mounted into a stud, these shelves are very sturdy and have been tested to hold 85 pounds. Dimensions: Width: 12 Height (including brackets): 4 Depth: 9 Pictured is a shelf with Red Mahogany-stained wood and Gray burlap.
